The Mac may be great but after 20 years on Windows, it's not intuitive to me. I am using a recently purchased Mac Book Pro. Stumbling around but getting the hang of things until I tried to organize my photographs in an external drive. I read the reviews and settled on a Western Digital, My Passport Essential SE. Plugged it in and cannot for the life of me figure how to start setting up folders. I have seen reference to formatting issues, but I purchased a Mac compatable external drive. Could some kind soul in the spirit of the season help out of this quarmire! Thanks.
